Open the spray bottle, fill it halfway with hot water, and add a small squirt of liquid soap. Plug the bottle with your thumb, and shake it vigorously. Empty the bottle, and rinse it several times.

Add the ingredients

Pour 1/2 quart of room-temperature white vinegar into the spray bottle. Add two drops each of orange, lemon, tea tree and peppermint essential oils. If you do not have one of these essential oils, omit it, and add an extra drop of the others.

Mix the cleanser

Cap the bottle tightly, and shake it for 45 seconds. Open the spray nozzle, and squirt the cleanser into the air in front of your face. If you wish to reduce the vinegar smell, add four additional drops of essential oil. Do not dilute the cleanser with water, as doing so weakens its antibacterial power. Use the solution immediately, and refrigerate any unused cleanser.
